A 24 year old woman is not considered as being a middle aged woman. She's considered a young woman because the life expectancy of women is higher than it has been in the history of mankind on this planet.
Because she is.
24 is not middle age. She is a young adult.
24 years old is not middle age unless you expect to be dead by 48. Middle age is usually considered around 40-45 for women. Most will live into their nineties. Old age is over 65, but many of us do not feel old before 75 or 80. Scientifically, the best year of most people's lives is 33, but even that is pretty subjective.
Do you have ANY idea how ridiculous you sound?
24 IS young...middle age would be 38 or more I think.
You really are totally obsessed with this ridiculous idea, aren't you?
24 is very young. Middle aged is over 45.
More to the point is why would YOU have such stupid ideas?
Maybe you have learning difficulties, I don't know. But you really need to get some help.
because she is young and not middle aged, perhaps
Because according to the Oxford English Dictionary middle age is between 45 and 65: "The period between early adulthood and old age, usually considered as the years from about 45 to 65." The US Census lists the category middle age from 45 to 65. Merriam-Webster lists middle age from 45 to 64, while prominent psychologist Erik Erikson saw it starting a little earlier and defines middle adulthood as between 40 and 65. The Collins English Dictionary lists it between the ages of 40 and 60, and the Diagnostic and Statistical Manual of Mental Disorders – the standard diagnostic manual of the American Psychiatric Association – used to define middle age as 40 to 60, but as of DSM-IV (1994) revised the definition upwards to 45 to 65.
